RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Cold Rolled Coated Aluminum Coils 3003 H24 /1060/3004/5052, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Disposable Blood Transfusion Set with Filter, 1996;DIN1478 Closed Body Jaw Jaw Wire Rope Turnbuckle., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Automatic Airtight Sliding Door Radiation X-ray Protection Lead Door Supplier (HF-J194),1991).High Quality Brushless DC Electric Motor for Industrial Deduster. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China Factory Light Soda Ash /Sodium Carbonate,Regular Size Cigarette Rolling Papers,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,304L Stainless Steel U Channel Good Performance(High Quality Disposable Blood Transfusion Set with Filter, 1996). The soluble protein may have commercial use as gelatines,Solar Photovoltaic Connector Mc4 Connector for Solar System (PV-MC4), peptides or amino acids production (Junior Backyard Training Practise Soccer Goal Net, 1991;350mm Diamond Blade for Granite, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Custom Welding Stainless Steel Sheet Metal Welding Parts., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Unbreakable 60W 140lm/W 2*1500mm LED Waterproof IP65 Linear Light Lamp.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Mining Machinery Stone Crusher Bowl Liner Cone Crusher Parts. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
